From the poster,
Level 210, NG+3 Vigor 12/Mind 60/Endurance 50/Str 12/Dex 40/Int 99/Faith 8/Arcane 8
Using Carian Regal Scepter +10 (Spinning Weapon is the default Ash of War) & full Rennala cosplay. Spells are (in order of appearance) Comet Azur, Shattering Crystal, Carian Slicer, and (of course) Rennala’s Full Moon.
I used Wondrous Physick with Cerulean Hidden Tear & Magic-Shrouding Cracked Tear before entering the fight.
Talismans are: Primal Glintstone Shard, Graven Mass Talisman, Magic Scorpion Charm, and Radagon Icon (ironic lol)
40 Dex + Radagon Icon is why I’m able to cast so fast.
Vigor 12 because he started as a Samurai.
